Patent DE-2747006-A1 (DE)
Title: Window with rotation limiting lever and lock - has top lever covered keyhole accessible only in certain lever position to prevent unlocking from outside
Inventor: GAUGG JOHANN
IPC: E05C17/24
Filed: 1977-10-19
Abstract: The rotatable window or door has a limiting stop. The blocking lever system is pivoted on a moving frame parallel to the frame's rotating axis. This lever system is housed in grooves in moving and fixed frames. The blocking lever end can be held in the fixed frame by a key-actuated lock. The lock cannot be operated from outside through the open window gap since the keyhole of the lock is situated in the area covered by the broad blocking lever when the window is open. The keyhole becomes accessible only in a certain position of this lever corresponding to partial opening of the window.

Title: Plastic roll cooling - by contact with subliming granular solid material
IPC: F26B13/18
Filed: 1977-10-22
Abstract: A roll, specially one made of plastics, for use in the treatment of paper or textile webs, is cooled on its surface by keeping it in contact with a colder material which sublimates at atmospheric pressure and at the roll temp. This is a most effective dry system of roll cooling which dissipates and heat at the point where it is generated.

Title: Logic circuit receiving two three-level input signals - has diode bridge rectifier to produce output signal only when input signals have opposite polarities
Inventor: SCHLEIFER WOLF DIETER DIPL ING
IPC: H03K19/082
Filed: 1977-12-12
Abstract: The logic circuit, for two triple-level input signals, i.e. positive zero or negative has a double-level output, i.e. zero and either positive or negative. It adopts one output level only when one of its input levels is positive and the other negative. A 4-diode rectifier bridge (4) receives the two input signals (1, 2) at its ac inputs (5, 6) and drives with its dc outputs (13, 14) two complementary transistors (17, 18) connected together by their emitters. The collectors of the transistors produce the output signals and are coupled via resistors (19, 20) to positive and negative supply poles.

Title: Abrading tool with discontinuous diamond pattern - obtd. by electro-nickel bonding diamond particles to surface having interspersed metal and resist zones
Inventor: GREEN THOMAS R
IPC: B24D7/06
Filed: 1978-01-18
Abstract: An abrasive tool with a discontinuous diamond pattern on the surface is made by electrochemically depositing a metal on a surface of a substrate having interspersed metal zones and non-conductive resist zones. Diamond particles are then non-selectively distributed over the surface, and Ni is electrodeposited on the horizontal surface to bond the diamonds to the metal zones. The substrate is then titled to remove the diamonds which are not bonded to the resist zones and further Ni is electrodeposited to bond the diamond particles. Used for abrading discs for grinding and polishing opthalmic lenses. The discontinuous diamond pattern economises on diamond and is easily produced.

Title: Spring mattress with separate spring cores - has foam layers covering separating areas preventing undue weak on springs
IPC: A47C27/05
Filed: 1978-06-24

Title: Electrical contact strip for terminating conductors - is formed from strip metal in one piece and grips outer sheath and core
Inventor: KRESSE FRANZ
IPC: H01R4/18
Filed: 1979-09-04
Abstract: The contact strip (1) has a strainer (4,5) for the electrical connection (6) with the cable (2). The contact strip is also perforated at one end and folded across its length, so that the bending line (14) runs central through the perforation. At the longer of the two side pieces (5), an electrical ferrule (6) is formed in the length direction of the cable (2).
